The BQ24780S is an integrated circuit in a QFN package, used in battery charging circuits on laptop motherboards. The component is intended for service shops and electronics technicians who repair damaged power sections.

Application

The chip acts as a battery charge controller. When a laptop does not charge its battery or does not recognize the power adapter, one possible cause is a damaged controller. Replacement requires soldering on a repair station, so we direct this component to people with the right equipment.

• BQ 24780S marking on the top surface,
• small dimensions, typical of SMD surface mounting.
